An abnormal digital flexor tendon sheath was present in the mid to lower metacarpal region in a horse. Positive contrast radiography showed that it communicated with the carpal synovial sheath but not with the digital synovial sheath. Cytological and physical analysis of fluid from the abnormal tendon sheath revealed that it was compatible with normal synovial fluid. This abnormal tendon sheath was probably a congenital anomaly.
